Claims.

This invention relates to fans, and more particularly to foldable fansof the type wherein separate sheets are united to produce the foldableconditions.

An object s to create a simple and inexpensive fan of this kind whereinthe separate sheets are slidably interlocked with each other. Attentionwill be directed to interlocking conditions produced by merely foldingand lapping the side margins of adjacent fan sections, so as toeffectively unite the several sections, and at the same time limitpivotal movements thereof.

With the foregoing and other objects in View, the invention comprisesthe specific combination and arrangement of details herein shown anddescribed to illustrate one form of the invention. However, the scope ofthis patent extends to variations and modifications more broadlydescribed by the terms employed in claims hereunto appended.

Fig. 1 is a front view of a sectional fan embodying features of thisinvention, with a portion of the middle section broken away to moreclearly show an interlocking condition at folded side margins ofadjacent fan sections.

Fig. 2 is a section taken on the line 2--2 in Fig. 1.

Fig. 3 is a section on the curved line 33 in Fig. 1.

Fig. 4 is a front view of the fan in a folded condition.

Fig. 5 is a horizontal section on the line 5--5 in Fig. 4.

Fig. 6 is a rear view of the middle section, showing its inturned sidemargins.

Fig. 7 is a rear view of one of the side sections, with dotted linesshowing an inturned side margin to be interlocked with the middlesection.

In this form of the invention there is a middle section A pivoted to andslidably interlocked with side sections B and C. The several sections,when interlocked with each other as shown in the drawings, have inturnedreinforcing flanges and, therefore, can be made of relatively thinpaper, or other weak sheet material. However, in Figures 2, 3 and 5 thethickness of the most desirable sheet material is enlarged to moreclearly show the interlocking conditions.

The middle fan section A is formed by a sheet of material havingtapering side edges 8, and folded side margins 9 extending inwardly fromsaid side edges 8. The lower ends of the folded side margins 9 may belapped at a reduced lower portion of the tapering middle section, asshown in Fig. 6.

I will now refer to details of the tapering side sections B and Cextending from the middle section A. The section B has a folded innerside margin in arranged within and embraced by one of the folded sidemargins 9 of the middle section A. The section C at the opposite side ofsection A is likewise provided with a folded inturned inner side marginl l arranged within and embraced by a folded side margin 9 of saidmiddle section A.

The several folded side margins 9, l0 and II can be conveniently lappedat the lower portion of the fan, as shown most clearly in Fig. 2 toreceive a pivot I2 which extends through all of these lapped margins andalso through body portions of the main sections A, B and C.

The pivot I2 is conveniently formed by a hollow eyelet, but any othersuitable pivot may be employecl.

The inturned side margins embrace each other to limit pivotal movementsin opening the fan, while also serving as reinforcements for the sheetmaterial.

When the fan is closed, as shown in Fig. 4, extensions l3 can be graspedand pulled away from each other to open the fan. These extensions l3project from outer edges of the fan sections B and C.

I claim:

1. A foldable fan comprising separate fan sections pivotally connectedtogether, each of said sections havin a folded side margin lapping andslidably interlocked with one of its companion fan sections to limitrelative pivotal movements of said separate fan sections.

2. A foldable fan comprising separate fan sections pivotally connectedtogether, each of said sections having a folded side margin lapping andslidably interlocked with one of its companion fan sections, and each ofsaid folded side margins being arranged within and embraced by thefolded side margin of an adjacent fan section, so as to loosely unitethe adjacent sides of said separate fan sections.

3. A foldable fan comprising fan sections formed by separate anddistinct sheets slidably interlocked with each other, each of saidseparate sheets having a folded side margin lapping and slidablyinterlocked with one of its companion fan sections, each of said foldedside margins being arranged within and embraced by the folded sidemargin of an adjacent fan section, so as to loosely unite the adjacentsides of the separate fan sections, and a pivot connecting the lowerportions of said fan sections.

4. A foldable fan comprising a middle fan section formed by a sheet ofmaterial having tapering sides and folded side margins extendinginwardly from said tapering sides, the lower ends of said folded sidemargins being lapped at a reduced lower portion of said tapering middlesection, tapering side sections formed by separate sheets of materialextending from said middle section, each of said side sections having afolded inner side margin arranged within and embraced by one of thefolded'side margins of said middle fan section, the several folded sidemargins of said sections being lapped at the lower portion of the fan,and a pivot extending through said lapped margins so as to pivotallyconnect the separate fan sections.

5. A foldable fan comprising middle and side sections pivotallyconnected together and having inturned side flanges slidably interlockedwith each other to limit the separation of said side sections from saidmiddle section, each of said side sections having an extension at itsouter edge to be grasped in separating the side sections.
